| 摘 要： | 以ZSM-5、Y型、MCM-41分子筛为载体,采用离子交换法制备了一系列用于汽油脱硫的负载金属离子的改性分子筛吸附剂。对不同的吸附剂作了X-射线衍射和比表面积分析,考察了静态吸附条件对其脱硫性能的影响。结果表明,不同吸附剂对噻吩的吸附效果不同,CuY的效果较为明显,并得出适宜的吸附条件:常温,常压,剂油质量比为0.15。通过对再生前后吸附剂CuY的变化分析,对吸附脱硫的机理进行了探讨。

| Abstract: | A series of adsorbents involving modified ZSM-5,Y,MCM-41 molecular sieves were prepared by ion-exchanging method for gasoline desulfurization.The composition and specific surface area of the adsorbents were determined by XRD technique.The effect of adsorption conditions on the desulfurization performance of the adsorbents was studied.The results show that the desulfurization performance varies for different adsorbents,CuY performs the best and the optimum adsorption conditions is ambient temperature,atmospheric pressure and mass ratio of adsorbent to oil ratio of 0.15.By analyzing the varations of the adsorbent CuY through regeneration process,the mechanism of adsorptive desulfurization was investigated. |
